IMPROVEMENT IN HARVESTERS.

To all whom it may 'concern Be it known that I, L. M. BATTY, of Canton, iii

the county of Stark, and 'State of Ohio, have invented certain new and Auseful Improvement-s in Harvesters; and I do hereby declare that the following is a full, clear, and exact description of my invention, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon, of which drawings- Figure l is a plan of a liarvester-barand attachments, showing my improvements.

Figure 2 is an end elevation of' the same.

Figure 3. is a, sectional elevationof the same, takenl through the finger-bar, and looking toward the toe of said bar.

Figure 4 is a detached 'detail of' the apron-driving roller and ratchet-wheel.

`In the construction 'oraharvesteig with a inecham ical delivery for the cut grain from the machine into sheaves, ou the ground, it is desirable that the dclivery-mechanism be brought as near as possible to the cutters, in order, that'as the grain is cnt, itshall fall fairly on tothe' delivery-mechanism, so that as it is carried off, the buts of the grain shall not diag on the ringer-bar, nud thus injure the evenness ofthe sheai.

To eli'ect this result is the object of my invention, which consists, rst, in the combination, with a han vesternger-bar, constructed with a concave rear face, of a shaft or roller arranged parallel to the-concave face of the hoger-bar, and iitting in said face, whereby the desired result is very simplyaud cheaply effected. The second part of my invention consists in the novell mode of' arranging and operating an endless apron in the rear of the finger-bar, upon which the grainfalls as it is cut by the machine, and by which it is delivered in sheaves in the rear of the machine, whenever desired, by the driver on the machine, in an easy and very successful manner.

'lo ena-ble'others skilled in the art to make and use my invention, I will4 proceed to describe its construction and operation. v

The finger-bar A'is 'of the general form shown, and is made of plate-iron or steel, curved into the con cave form shown iu'g. 3, the coucavity being on the rear face of the bar. As is there shown, the general forni of the front of l the 'bar is that of a semicircle, but this cache varied to suit any requirements oi' construction, the point being that the bar shall, in all cases, he concave on the rear face, so as'to admit the front ofthe delivery-mechanism, and that the upper side of the bar shall not extend further back than is necessary to cover the space between the rear face of the bar and the front halt' of thefront roller of the delivery-mechanism, so as to avoid forming a face on the finger-bar, on which thebuts of the grain would drag when the gevel was to be delivered.

The form of the blu" insures all the lnecessary vertical stiffness, and if more lateral stiffness is required than would be obtained in a semicircular section ot' bar, one edge can be prolonged into the base-plate F, by which the lateral stiiuess can be increased, and the apron be protectedom injury.

The fingers' B are made to fit the front and under side of the bar A, towhich they are secured by rivets or screws in an ordinary manner.

The toe-plate E has its front end rounded up, so as ro lit into the concave rear face of the bar A, to which it can be firmly secured by asingle bolt, I), as the fitting of its front end into the concave 'ace of" the bnrV will .effectually prevent -either a vertical or lateial movement of the plate around the bolt. Y

The frame-piece D has its front end rounded ofl, so as to fit in the concave face of the toe-plate E, to A,which it is secured by one or more screws, d the' fitting of the end of said piece under the concave face of the plate E materiallyv aiding in obtaining a stiff connection of plate and piece, as is readily seenV The heel-shoe R is notched down and faced to receive the bar A, which fits' into it, as shown in fig. 2, where it is` retained by the plate S, which is curved up at the end, to fit inthe concave -facc of' the bar A, and is held by ai screw, a, passing through it into the shoe R.

The frame-piece L is rounded off lat the end, to t `up under the concave face of the plate S, and is secured to said plate by a screw or bolt, arranged similarly to the' bolt d, in the piece D'.

The roller C is arranged in the concave face of the bar A. by journals, which workin boxes in the pieces D and L, andthe driving-apron roller H is secured ou a. shaft, L', working in boxes at the other ends of the pieces D L.

llhe apron G, of cloth, leather', or other suitable material,l passes around the rollers C H, as shown, and on it the grain falls as it is cut. Y

The ratchet-wheel I is secured at the end of the shaft k, and is caused to rotate by the rock-b ar M, whichis held over the `ratchet-wheel' by the notched guide-plate J, as shown in fig. 4.

The teeth on the ratchet-wheel I'and rock-bar M are constructed and arranged as shown, so that as the rock-bar M is moved. backward from the finger-bar, the roller H will be revolved, and the apron G moved backward to discharge its gathered loa-d of grain but in the forward movement of therock-bar no movement of the apron G will he effected. Y

'lhe bar M is curved up at its front end, as shown, and is provided with a hole in' which the bent end ol' the rock-lever P is secured, as shown in g. 1w.

The other end Aof the rock-lever l is bent at right angles, and secured in the lugs Q Q, on the heel-shoe 1t, thus' sewing as a journal or rock-shaft for the lever P. f

The rod 0 is attached to the bent end of the rocklever P, and extends forward or backward, (according as the machine is arear-or front-cutting machine,) to

'can cause `the apron G to discharge its gathered load,

as is readily seen.

By givin gl to the rock-bar M the upward turn shown at its front end, the back pressure applied at the end of said bar causes a downward pressure of the saine over the-Iratchet-wheel I, and thus insures the interlocking of the teeth on said rock-bar and ratchetwheel.

. From the foregoing description it is evident that by making the inge-bar A concave o n the rear face, I am enabled to bring the roller C much nearer to the cutters in the ngers B than Awould be practicable wit-l1 the ordinary forfn of finger-bar, and that bythis means the apron G is brought up so close to the cutters that the grain falls well over the bar A on to the apron G,-

and hence can be easily taken off by said apron, as before described.

.The roller C, or a similar shaft, with larger journals, could be used as the back piece of the common dropper, or for any purpose requiring the use of a shaft or roller parallel to the .cutter-bar, and close up to the cutters.

I am aware that finger-bars have been before constructed with Va concave rear face; hence I lay no claim to such finger-bars, except in combination with a shaft or roller, as is herein described.

I am also aware that aprons ,have been before usedv for delivering grain fromharvesters; hence I make no claim to the apron G, except when arranged and operated as shown; nor do I confine myself to thei pre'- cise construction here shown for producing the reciprocating motion of the rock-.bar M, as any mechanic could easily devise other devices for accomplishing the same result; but

the movement of Vhat I do claim herein asnew and of my invention, arid desire to secure by Letters Patent, is-

1. The combination, with a Aharvester finger-bar, constructedwith a concave rear face, of atoe-plate, fitting into Vthe concave rear face of the finger-bar, and secured to the edge thereof', and a frame-piece for the delivery-mechanism, tting inthe'concavity in the toe-plate, and secured to said plate, substantially as is herein specified. Y

2. The combination, with a harvester finger-bar, constructed with a concave rear face, of a heel-shoe, notched and faced to receive .thengenban and a retainingplat-e, fitting into the concave rear face of the 1ingerbar', and secured to the heel-shoe, substantially as is herein specied. I l 8. The combination, with: a harvester nger-bar,

constructed with a concave rear face, of a shaft or roller, arranged parallel to the finger-har, and in the concave rear face of the same, substantially as is here- 'in specified.

4. The combination,in a harvester, of a finger-har, constructed with a concave rear face, a roller, arranged in said concave. face, a driving roller, arranged between standards extending front said finger-bar, and a dropping-apron7 arranged around said rollers, substantially as is herein specified.

5. The reciprocating rock-bar, acting on the ratchetwheel on the shaftof the driving-apron roller, and actuatedyby the driver 'on his seat on the machine, for the purpose of operating an endless dropping-apron for harvester-s, substantially as is herein specified.

As evidence that I'claim the foregoing,1 have hereunto set my hand, in the presence ofv two witnesses. this 28th day of September, A, D. 1869.
